A small study of 25 healthy people without heart disease found detectable changes in the heart's electrical system when the participants were exposed to polluted air.
The findings suggest that air pollution may interfere with the heart's ability to reset its electrical properties in an orderly manner, said the researchers. This can lead to arrhythmias, which can cause sudden cardiac death in some people.
